PYROTECHNIC DEVICE.

Application led October 27, 1924. Serial No. 746,115.

To all whom t may concer/L:

Be it known that I, l/ViLLIAM linunnnn, a citizen of the United States, residing in Fort Dodge, in the county of `Webster and State of Iowa7 have invented a certain new and useful Fyrotechnic Device, of which the following is a specification.

rIlhe object of my invention is to provide a pyrotechnic device wherein the various parts can be collapsed and placed in a minimum package for shipping and storage purposes, the parts being of simple, durable and comparatively inexpensive construction.

Still a further object is to provide a number of bars connected together by links wherein the parts may be spaced apart or moved close together, as desired, for supporting pyrotechnic candles or lights for display purposes.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure l is a plan view of my pyrotechnic device arranged so that the words One law are exhibited or displayed through the use of my device.

Figure 2 is a view of the device shown in Figure 1 with the parts collapsed.

Figure 3 is a back view of a portion of the device shown in Figure 2, showing the link connections.

Figure 4 is a back view of a slightly modified form of device wherein single links are connected to the supporting bars; and

Figure 5 is a detail, sectional view taken on line 5 5 of Figure 1.

In the accompanying drawings, I have used the reference numeral 10 to indicate supporting bars which are connected together by toggle links 11. The links 11 are arranged near the top and bottom of the bars 10 and can be folded up so that the bars rest side by side or may be spaced apart, all as clearly shown in Figure 3 of the drawings.

The bars can be connected together by links of various sizes so that in case it is desired to form any particular letter or word, the space between such letter or word can be had.

In Figure 1 of the drawings, I have shown the words One law and the O is sepa-A rated from the N by a` toggle link, which is longer thanthe links connecting any two of the other bars 10 togethenwvhich form parts of the letters O or N.

rihe word One7 is separated from the word Law by links of considerable length.

Placed upon the bars 10 may be suitable pyrotechnic candles 12 held inposition by nails 13 or the candles 12 may be glued to the rail or bars 10.

The bars 10, when spaced apart as shown in Figure 1, have the words One law thereon and as the candles 12 are illuminated the letters of the words One law will be clearly visible.

The candles 12 are all connected together y by fuses 11i and a lighting fuse 15 is' also provided. 1 Y i The lighting of the fuse 15 will cause all of the pyrotechnic candles 12 to function.

In the arrangement of the letters A and W,for1ning a` part of the word Law, I arrange the links 11 in different position on the bars l10 so as to permit some of the bars 10 to be inclined from vertical, as clearly shown in Figure 1 to get the proper effect for the particular letter.

The toggle links may be collapsed, which will cause all of the bars 10 to be brought side by side wherein the pyrotechnic device may be packed in a minimum amount of space.

- Large bars can be used for forming large signs.

In Figure 4 of the drawings, I have shown the bars 10 as being directly connected by single links 16 arranged near the top and bottom thereof, which will cause the bars 10, when collapsed to be staggered somewhat relative to each other and yet when the links are in outspread position, all of the bars 10 will be in substantial alignment.

Then a single link 16 is used, then of course, it requires a little more space to pack the entire pyrotechnic device in than when a double or toggle link 11 connection is used.

The advantage of my structure resides in the fact that I am able to form any letter with the use of the bars and links, and yety l.
